Isaias 45:16

In Genesis: “And God said unto Jacob, Arise, and go up to the place of Bethel, and dwell there; and make there an altar to that God who appeared unto thee when thou fleddest from the face of thy brother Esau.” Also in Isaiah: “Thus saith the Lord, the God of Sabaoth, Egypt is wearied; and the merchandise of the Ethiopians, and the tall men of the Sabeans, shall pass over unto Thee, and shall be Thy servants; and shall walk after Thee bound with chains; and shall worship Thee, and shall pray to Thee, because God is in Thee, and there is no other God beside Thee. For Thou art God, and we knew it not, O God of Israel, our Saviour. They shall all be confounded and fear who oppose Thee, and shall fall into confusion.” Likewise in the same: “The voice of one crying in the wilderness, Prepare ye the way of the Lord, make straight the paths of our God. …

Therefore the Most High God, and Parent of all, when He had purposed to transfer His religion, sent from heaven a teacher of righteousness, that in Him or through Him He might give a new law to new worshippers; not as He had before done, by the instrumentality of man. Nevertheless it was His pleasure that He should be born as a man, that in all things He might be like His supreme Father. For God the Father Himself, who is the origin and source of all things, inasmuch as He is without parents, is most truly named by Trismegistus “fatherless” and “motherless,” because He was born from no one. For which reason it was befitting that the Son also should be twice born, that He also might become “fatherless” and “motherless.” For in His first nativity, which was spiritual, He was “motherless,” because He was begotten by God the Father alone, without the office of a mother. …

That these things should thus take place as I have set them forth, the prophets had before predicted. In the writings of Solomon it is thus written: “The womb of a virgin was strengthened, and conceived: and a virgin was impregned, and became a mother in great pity.” In Isaiah it is thus written: “Behold, a virgin shall conceive, and bear a son, and ye shall call His name Immanuel;” which, being interpreted, is God with us. For He was with us on the earth, when He assumed flesh; and He was no less God in man, and man in God. That He was both God and man was declared before by the prophets. That He was God, Isaiah thus declares: “They shall fall down unto Thee, they shall make supplication unto Thee; since God is in Thee, and we knew it not, even the God of Israel. …

38. Again, how clear is the declaration made by God the Father through Isaiah concerning our Lord! He says, For thus saith the Lord, the holy God of Israel, Who made the things to come, Ask me concerning your sons and your daughters, and concerning the works of My hands command ye Me. I have made the earth and man upon it, I have commanded all the stars, I have raised up a King with righteousness, and all His ways are straight. He shall build My city, and shall turn back the captivity of My people, not for price nor reward, saith the Lord of Sabaoth. Egypt shall labour, and the merchandise of the Ethiopians and Sabeans. Men of stature shall come over unto Thee and shall be Thy servants, and shall follow after Thee, bound in chains, and shall worship Thee and make supplication unto Thee, for God is in Thee and there is no God beside Thee. …
